Cierre primario en trauma de colon / Primary closure in colon trauma

RESUMEN

Objetivo: Informar si la evolución > 6 horas, grado de contaminación y lesión, sitio anatómico lesionado, PATI (penetrating abdominal trauma index) > 25 y presencia de otras lesiones en trauma de colon, se asocian a mayor morbimortalidad en pacientes con lesión colónica a quienes se les realizó cierre primario. Material y métodos: Estudio prospectivo, observacional, longitudinal, descriptivo, en el Hospital Central “Dr. Ignacio Morones Prieto”, San Luis Potosí. Se incluyeron pacientes con trauma abdominal sometidos a cirugía que presentaron lesión colónica. Análisis estadístico básico con χ2. Resultados: 481 pacientes fueron intervenidos por trauma abdominal; 77 (16.1 %) tuvieron lesión colónica, de los cuales 90 % (n = 69) se intervino en las primeras seis horas; 91 % fue lesión penetrante. El colon transverso fue el más lesionado (38 %, n = 29); las lesiones grado I y II representaron 75.3 % (n = 58). Se efectuó cierre primario en 76.66 % (n = 46), resección con anastomosis en 8.3 % (n = 5) y colostomía en 15 % (n = 9). Hubo lesiones asociadas en 76.6 % (n = 59) y contaminación en 85.7 % (n = 66); 82.8 % (58) tuvo PATI < 25; complicaciones asociadas al procedimiento operatorio, 28.57 % (n = 22); reintervenciones, 10 % (n = 8); estancia hospitalaria promedio, 11.4 días; mortalidad no relacionada a lesión de colon, 3.8 % (n = 3). Conclusiones: El cierre primario es un procedimiento seguro para el tratamiento de lesiones colónicas. Los pacientes con cierre primario presentaron menor morbilidad (p < 0.009). Los pacientes con cirugía en las primeras seis horas (p < 0.006) y estabilidad hemodinámica (p < 0.014) tuvieron menor riesgo de complicación.

ABSTRACT

BACKGROUND: Primary repair of colon injuries is an accepted therapeutic option; however, controversy persists regarding its safety. Our objective was to report the evolution and presence of complications in patients with colon injury who underwent primary closure and to determine if the time interval (>6 h), degree of injury, contamination, anatomic site injured, PATI (Penetrating Abdominal Trauma Index) >25, and the presence of other injuries in colon trauma are associated with increased morbidity and mortality. METHODS: This was a prospective, observational, longitudinal and descriptive study conducted at the Central Hospital "Dr. Ignacio Morones Prieto," San Luis Potosí, Mexico, from January 1, 2003 to December 31, 2007. We included patients with abdominal trauma with colon injury subjected to surgical treatment. chi(2) was used for basic statistical analysis. RESULTS: There were 481 patients with abdominal trauma who underwent surgery; 77(16.1%) had colon injury. Ninety percent (n = 69) were treated in the first 6 h; 91% (n = 70) were due to penetrating injuries, and gunshot wound accounted for 48% (n = 37). Transverse colon was the most frequently injured (38%) (n = 29). Grade I and II injuries accounted for 75.3% (n = 58). Procedures included primary repair (76.66 %) (n = 46); resection with anastomosis (8.3%) (n = 5); and colostomy (15%) (n = 9). Associated injuries were present in 76.6% (n = 59). There was some degree of contamination in 85.7% (n = 66); 82.8% (58) had PATI <25. Complications associated with the surgical procedure were observed in 28.57% (n = 22). Reoperation was necessary in 10% (n = 8). Average hospital stay was 11.4 days. Mortality was 3.8% (n = 3); none of these were related to colon injury. CONCLUSIONS: Primary repair is a safe procedure for treatment of colon injuries. Patients with primary repair had lower morbidity (p <0.009). Surgery during the first 6 h (p <0.006) and in hemodynamically stable patients (p <0.014) had a lower risk of complications.
